3 is one of the functions
Triangle has 3 sides.
1st side: 5.6 yards
2nd side: 7.1 yards
3rd side: x
7.1 yards - 5.6 yards = 1.5 yards
7.1 yards + 5.6 yards = 12.7 yards
x is between 1.5 yards and 12.7 yards.
1.5 < x < 12.7
Yes, you can look at the x-value on the graph and then look at the number of squares up or down the corresponding y-value is
Your final answer will be x=-7 and y=4. Included a pic. Sorry about the chicken scratch and torn up envelope.
A is the correct answer. PEMDAS for single step and double step equations alike.
